Introduction and Understanding about Acceptable Solutions of Foundations Design in NBC-2010

国际上普遍认为《加拿大国家建筑法规》NBC-2010在技术法规中构思比较先进。该法规基于目标编制,分为A、B、C三部分,A部分为法规的范围、目标、功能陈述及合规性,B部分为被视为能够满足目标及功能的可接受方案,C部分为与法规实施相关的管理规定。本文详细介绍了B部分中关于基础设计的可接受方案内容及相应的功能陈述与目标,并以地质勘察内容为例,对可接受方案如何通过实现功能从而达成目标进行了说明。NBC-2010的可接受方案具有目标性及定性不定量这两个突出特点,其编制原则、方法及技巧可供国内编制全文强制标准工作参考,也有利于国内未来技术法规的理解、宣传、普及与实施。

The Code is based on the objectives and divided into Division A,Division B and Division C. Division A includes application,objectives,functional statements and compliance,Division B includes acceptable solutions that they are considered to meet the objectives and functional statements,and Division C includes administrative provisions related to implement the Code. In this paper,the acceptable solutions and relevant objectives and functional statements about foundations design in Division B are introduced in detail,and the process that acceptable solutions how to realize function to achieve objectives is explained with geological survey as a case.The acceptable solutions in NBC-2010 have two features,one is objective-based,and the other is qualitative but not quantitative. The principles,methods and skills of NBC-2010 could be referenced when domestic full text compulsive standard is writing,and it will help to understand,broadcast,popularize and implement technical regulation in China in the future.
